I am trying to map a one to one relationship between a table and a view. However, the view doesn't contain the primary ID of the table, just another field that is unique. The view is legacy that does some calculations based on some tables (ugh!).

Anyways, what we have is something like this (extremely simplified):


These need to be joined across the invoice_id column, but it is not declared as an identifier in Order.

We have the following hibernate mapping file(s):

When I try to retrieve it, it tries to join across the Order.id field (OrderInvoice.invoiceId = Order.id). Can it be setup to use invoiceId without adding invoiceId to a composite key in the Order mapping?

Thanks!
